Abstract
A vehicle includes an internal combustion engine, an electric machine, and a controller. The electric machine is rotatably coupled to the engine and is configured to deliver electrical power to electrical accessories. The controller is programmed to, in response to a control signal loss between the electric machine and the controller, limit torque output of electric machine to less than a torque threshold that corresponds to the power threshold. The controller is further programmed to, in response an accessory power demand being greater than the power threshold, control the engine to power the electric machine to increase the torque output of electric machine to greater than the torque threshold to meet the accessory power demand.
